Ku qor 321 (UNS S32100) ee tuubooyinka gariiradda
Sharaxaada
Nooca 321 waa titanium chromium nikkel austenitic ahama birta xasiloon oo leh iska caabin daxalka oo la mid ah 304/304L.Darajadan waxaa sida caadiga ah loo isticmaalaa 800-1500˚F heerkulka kala duwan halkaas oo ay ka xasilin lid ku ah roobabka chromium carbide by kordhinta titanium, taas oo keenta in roobka ee carbides titanium.Nooca 321 wuxuu leeyahay iska caabbinta daxalka intergranular aad u fiican ka dib soo-gaadhista heerkulkan kala duwan, darajadanna waxay ka hortagtaa oksaydhka ilaa 1500˚F waxayna leedahay gurguurta iyo kadeedka dilaaca guryaha ka badan 304/304L.Waxa kale oo ay leedahay adkeysi heerkul hoose oo wanaagsan oo aan ahayn birlab ku jirta xaaladda la jeexjeexay.
